Mainly used in the refrigeration circuits of air conditioners, refrigerators, freezers and other refrigeration equipment.
Expansion valve controls the flow and pressure of refrigerant to enable vaporization and heat absorption
Four-way valve switches between cooling and heating modes by changing refrigerant flow direction
Solenoid valve controls refrigeration circuit on-off to ensure normal system operation
Core Features
Precise flow control to maintain stable cooling and heating performance
Material resistant to refrigerant corrosion, compatible with common refrigerants including R22, R410A, R32
Stable operation at low temperatures down to -40°C without jamming or leakage
Processing Notes
Internal flow passages must be extremely smooth with surface roughness below Ra0.4
Fitting clearance between valve core and body controlled within ±0.005 mm for precise flow control
Processing in dry, clean environment with strict moisture and oil residue prevention
Four-way valve reversing mechanism must be flexible and reliable with 0.5-1 second switching time
Comprehensive leakage and flow accuracy testing with ±5% adjustment error tolerance
Selection Criteria
Must be compatible with specific refrigerant type (R22, R410A, etc.)
Prioritize fast response and accurate opening characteristics
Choose branded valves originally matched with equipment for proven reliability
Inspect appearance for scratches, deformation, and verify welding joint quality
We utilize advanced Japanese and German equipment (CNC 5-axis and 6-axis machines) to serve customer needs. Maximum processing outer diameter: 60mm, minimum tolerance control: 0.001mm.
